摘要
本文提出在投影球内建立锥体单元统计系统,直接计算以产状表示的单元轴线与节理法线的夹角,统计该夹角小于单元锥角半角的数目。统计结果更合理、可靠。
The method involves directly calculating every one of the angles between each normal to one of the joints and every axis of the conical elements set up in the stereographic projection sphere and comparing the angles with half of the cone angles. The statistical results are more accurate.
